FAN FOR DIS- iNFEOTlNG PURPOSES.

SPECIFICATION forming' part of Letters Patent No. 757,684, dated April19, 1904.

Application filed July Z1, 1908. Serial No. 166 ,1145. (No mudelr)prevent the pressure in the reservoir from becoming too high or tomaintain the same at a predetermined pressure, a safety or reducingvalve 17 is provided. The, spring 18, which presses the valve-head 19into its seat, may be `adjusted by screwing the abutment 20 in or out. Y

From the foregoing the operation of the apparatus will be readilyunderstood. The reservoir 8 having been filled through a suitablefilling-orifice 21 until the same is about half full, the current isturned on, and the fan begins to rotate. At the same time the shaft 10and its crank are revolved, thus reciprocating the piston 13 of thecompressor, which forces air into the space above the liquid inthereservoir. The liquid immediately ascends the conduit 7 and from thereis delivered into the rotating shaft 2, from which it is discharged as aline spray at the oritice L1. The spray is immediately seized by theblast of the fan and being still further divided is carried by thecurrents of air from the fan into all parts of the room. 4

It will be seen that my invention provides a convenient way ofdistributing vapor throughout an apartment. By this means a roornsuchas, for example, a public auditoriummay be constantly supplied withdisinfectant, Vdeodorizer, or Aperfume in a very effective manner. vTheair in the room will be at all times thoroughly charged with the vaporor minute particles, and the purpose of the same will thus beaccomplished in a more satisfactory manner than by sprinkling the floorsor walls with a volatile liquid orby exposing such a liquid in openreceptacles. Other uses for the invention; will of course be suggestedaccording to circumstances.

' The form herein shown venient but not the onlyT embodiment of which myinvention is capable, and I therefore do T @ZZ whom t may concern.:

Be it known that I, WILLIAM W. ROSSITER, a citizen of the United States,residing in the borough of Brooklyn, city of New` York, county of Kings,and State of New York, have' invented certain new and usefulImprovements in Fans for Disinfecting and other Eur-poses,` of which thefollowing is a specification, reference being had to the drawingaccompany- 1o ing and forming panrt of the same. The invention whichforms the subject of my present application, while it pertains, broadly,to fans of any character, relates more particularly to electric fanscommonly used for ventilation and other purposes. f

The object of the invention is toprovide such a fan with means forloading the air-blast with vapor or minute particles of liquid. Thismaterial may be a disinfectant which it is desired zo to scatterthroughout the room in which the i fan is used or a perfume or any otherliquid,

according to the object sought.

To thse ends the invention consists of the novel features andcombinations hereinafter z5 described, and more particularly set forthin the claims.

Referring now to the drawing, which shows a convenient embodiment-of myinvention, 1 indicates the standard and casing in which the operatingmechanism of electric fans is usually located. The armature-shaft 2,upon which the fan-blad es 3 are mounted, is in the present case hollowor tubular and has at its outer end a constricted outlet-orifice 4. Atthe other 3 5 end is an inlet-orifice 5, to which is connected by asuitable coupling 6 a conduit 7 The latter extends to a pointadjacent-the bottom of a reservoir 8, suitably supported ,in the bottomof the standard. On the armature-shaft 4o is a gear-wheel 9, which by atrain of gears drives a crank-shaft 10, suitably journaled in thecasing. On the liquid-reservoir is an air-` compressor 11, consisting inthe present instance of a cylinder 12 and a piston 13, working therein.A pitman 14 connects the piston and the crank in the shaft 10. Suitablevalves struction herein described; but

What I claim is- 1. In a fan or blower, in combination, a hollow shafthaving an inlet-orifice, and having an outlet-orifice at the center ofthe rotating fan, a liquid-reservoir, a conduit connecting theinlet-orifice of the 15 and 16 in the piston and in the lower end of thecylinder enable the liquid in the reservoir to be put under considerablepressure by the reciprocation of the piston.

'In order to hollow shaft with the I regard as a con-` not considermyself limited to the exact con-YY f reservoir,means for driving thefan, and means for discharging liquid from the reservoir through theconduit, the hollow shaft, and the outlet-orifice, as set forth.

2. In a fan or blower, in Combination, a hollow shaft having aninlet-orifice, and having an outlet-orifice at the center of therotating' fan, a liquid-reservoir, a conduit connecting theinlet-orifice of the .hollow shaft with the reservoir, an air-compressorconnected with the reservoir, means for driving the fan, and means foractuating the compressor, as set forth.

3. In a fan or blower, in combination, a hollow shaft having aninlet-orifice, and having an outlet-orice at the center of the rotatingfan, a liquid-reservoir, a conduit connecting the inlet-oriiiee of thehollow shaft with the reservoir, a reciprocating air-compressor connected with the reservoir, a crank-shaft, a pitman connecting thecrank-shaft and the compressor, means for driving the fan, and means forrotating the crank-shaft, as set forth.

4. In a fan or blower, in combination, a hollow shaft having aninlet-oriiice, and having an outlet-orifice at the center of therotating fan, a liquid-reservoir, a conduit connecting the'inlet-orifice of the hollow shaft with the reservoir, means for drivingthe fan, means for compressing air above the liquid in the reservoir,and means for maintaining a constant pressure therein.
